What is the key symptom associated with Morton's neuroma?

Morton's neuroma is characterized primarily by the development of a painful condition in the forefoot, typically between the third and fourth toes. The key symptom associated with this condition is numbness or tingling sensation between the toes, especially the third and fourth toes. This occurs due to irritation and compression of the digital nerves in that area. Patients often describe a feeling of having a "stone" in their shoe, which contributes to the discomfort and numbness experienced.

Numbness can arise from increased pressure on the forefoot due to footwear (such as narrow shoes) or from activities that place strain on the feet. This symptom is a hallmark of Morton's neuroma and helps differentiate it from other foot-related issues, which may manifest with different sensations or localized pain. Understanding this key symptom is essential for effective diagnosis and treatment of Morton's neuroma in clinical practice.
